Today marks a huge milestone for Digg. Three reasons: First, because we’ve closed a $4 million Series A investment from Digital Garage. Second, because Digg has a new CEO, Gary Liu. Third, because Digg is leaving thebetaworks nest and moving into its own office space downtown.

The formal press release is here. I’ll add a little color, spiced with just a dash of sentimentality:

We’re incredibly excited to have Digital Garage as Digg’s leading investor, and as a strategic partner. DG is an Internet-focused operating and investing company based in Tokyo, and has a long history of success partnering with American tech companies(for example, LinkedIn, Twitter, and Path) to enter Japan and other Asian markets. We think the Digg model of [curation + technology] can find sizable and enthusiastic audiences around the world, and we’re thrilled to get to work with Digital Garage in making it happen.

Through it all, the Digg team has been incredible, and I want to thank them so effusively it’s embarrassing. Digg’s technologists, editors, designers, and business developers have proven to be absurdly talented, committed, and creative. With a very small number of people, our engineers, led by NYC’s best CTO, Mike Young, have built a sprawling and sophisticated technical infrastructure at vast scale with many interlocking components and interfaces, and that works extremely well. Digg sites and apps look and feel terrific thanks to the vision, clarity, and detail-obsession of Justin Van Slembrouck. Our editors, led by the brilliant and exacting Anna Dubenko, range widely and ingeniously across the Internet and through our powerful data tools to find and package the best stories and videos on the Internet. Not a day has gone by that they haven’t brought me (among millions of other users) delightful things I wouldn’t otherwise have discovered, along with actual LOLs from their headlines, kickers, and growing corpus of original pieces. Finally, the business team, newly led by the enormously gifted and energetic Won Kim, has invented a native business model for Digg, scrappily building it from zero to impressive. I’m tempted to name and praise every member of the team individually, but that’d make a loooong post.

Tying these teams all together since March has been COO Gary Liu. Gary and I overlapped at Google, and his career has taken him through startups to Spotify, where he led Spotify Labs and Ad Product Strategy. When we hired him, my hope was that he would prove to be the right next CEO to take the company from Series A to success at global scale. And indeed, I was right. Gary’s been an absolutely fantastic operating leader for the company, gifted at everything from team leadership to monetization strategy to operational execution to finance to product and marketing, and I’m thrilled to hand the reins over to him. Though I’m going to be an active executive chairman of Digg’s board, Gary is the right leader for Digg’s next chapters, and I couldn’t be more thrilled that he’s taken on the challenge.

And so as Digg gets ready to move into its own office in a few weeks, I’m returning to betaworks full-time, to get new initiatives off the ground. And I’m already more than a little wistful, preparing to miss the Digg team that’s been such a wonderful part of my day-to-day life for more than two years. Fortunately, not only do I still get the daily joy of Digg’s homepage, apps, videos, email, etc., but they’re letting me stay in the Digg Slack channel, which never, ever fails to crack me up.
